WASHING-MACHINE.

Specification of Letters Patent.

Patented Sept. 1, 1914.

- Application filed June 9, 1913. Serial No. 772,637.

To all whom it may concern:

Be it known that I, EUGENE. YAZEL, a citizen of the United States, and a resident of Vermilion, in the county of Clay and State of South Dakota, have invented certain new and useful Improvements in Washing-Machines, of which the following isa specification. v

This invention relates to *washing-machines.

The primary object of the invention is the construction of an improved washing-machine employing no paddles, plungers or reversed motion to injure the material being cleansed.

Another object of my invention is the production of a device of this class requir ing a minimum of power in operation.

A still further object is the production of a washing-machine inexpensive in manufacture, yet thoroughly reliable in operation.

\Vith these and other objects in view, the invention, consisting in the construction, combination andflnovel arrangement of parts, will be fully understood from the following description, reference being had to the accompanying drawings, forming a part of thisapp'licati'on, in which like characters of reference indicate like parts throughout the several views, of which,'

Figure 1 is a side elevation of ,a device constructed in accordance with my invention; Fig. 2 is a plan view of the same, with one of the covers omitted; Fig. 3 is a plan view of the external tub, with legs and other members omitted; Fig. 4 is a vertical section taken on the line 4-'& of Fig. 2; and Fig. 5

is a fragmentary perspective view partly in *section of the external tub with wringer of the spider, is a bolt, 10, which passes through the bottom of the external and is encircled by a gasket, or other; suitable packing, 12, adjacent the inner side of the bottom of said tub. A nut,,l1, turned upon the threaded end of thebolt and into firm engagement with the packing, firmly secures the tub to the supporting structure and prevents leaking around the bolt. The bolt, t0, also affords a suitable bearing for a vertical shaft, 13, the upper end of the bolt being recessed to admit the lower end of the shaft. The said shaft is encircled by an open-ended perforated cylinder, 14, soldered or otherwise secured to the bottom of a rotatable-tub, 15, the sidesof which are perforated. The cylinder is secured tolthe shaft, at the top by being riveted to arms,

l6 extending laterally: from a collar, 17, secured by a set-screw, 18, or otherwise, to the shaft; and at the bottom by a similar collar, 19, secured to the shaft by a set-' screw, 20, and provided with lateral arms,

21, downwardly-inclined and riveted to the bottom of the rotatable tub. The bottom of the rotatable tub has an opening concentric with, and of equal diameter to the cylinder. Dialnetrically within the top of the tub, G, is a cross member, 22, secured by bolts, 23, to an internal rim, 2-1, secured to the sides of the tub. WVithin the center of the cross member, 22, and a bearing plate, 35, rotates the shaft, 13, carrying a fixed bevel-pinion, 26, intermeshed with a bevcl gear, 27, secured upon a shaft, 28, provided with a crank, 29, or other suitable means for imparting rotation thereto, and journaled in suitable bearings, 30 and 31, upon the cross member. The bearing 31 is integral with the plate, 25. To the inner side of the tub, 6, are secured helically-disposed ribs, 32, which direct the circulation of the water downwardly, as will presently be made more clear. To the inner side of the bottom of the tub are secured scroll-shaped ribs, 33, extending from the sides of the tub to points near the center of the tub below the cylinder, 14. Covers, as 34, are secured by hinges, 35, on opposite sides of the cross member, 22, and normally rest upon the annular rim, :14, previously described.

A suitable member for attachment of a wringer, is clearly illustrated in Fig. 5 and comprises side brackets, 36, suitably secured to the outer side of the tub, 6, and supporting a back-board, 37, to which may be clamped the usual wringer; and a drainshelf, 38, having its front edge resting upon, and curved to conform to, the upper edge of the tub.

In operation, the material to be cleansed is placed within the circumferential compartment of the internal tub outside of the cylinder, 14:, and the tub partly filled with water. As rotation is imparted to the shaft 28, in the direction indicated by the arrows in Fig. 1, the internal tub will be caused to rotate in the opposite direction, and the water will be thrown radially through the material being cleansed and outwardly through the perforated periphery of the tub, and by coming into contact with the under sides of the helical ribs, 32, be forced downwardly against the concave faces of the scroll-shaped ribs, or water-guides, in the bottom, by virtue of which the course of the water is directed inwardly and thence upwardly within the cylinder, 14:, and

' through the perforated periphery thereof into the cleansing compartment; and thus the operation is continued, the water being constantly circulated through the material.

Having thus described my invention, what I claim as newand desire to secure by Lettors Patent, is,-

A washing-machine comprising an upright outer tub having helically-disposed ribs on the inner periphery thereof, an internal rim adjacent the upper edge thereof and water guides in the bottom thereof; an internal tub mounted for rotation within the outer tub and having a perforated periphery and a central bottom opening; an upright cylinder secured to and disposed coaxially within said internal tub and having a perforated periphery, said cylinder being of substantially the same diameter as said bottom opening and said water guides being scroll'shaped and positioned to approach the center of the tub from the periphery thereof in a gradually decreasing curve whereby little resistance is offered to the circulation of the water; and means for rotating said internal tub.

In witness whereof I have hereunto set my hand, this 2nd day of June, 1913, in the presence of two witnesses.

EUGENE YAZEL.
